1./ 'o uM whom it muy concern le it known that l.) DANIEL Lann, a citiwu oi? tie United States, and a resident o' 1, Thomasj in the county of Campbell und .State of Kentucky, have invented certain new and useful improvements in Stoves or liurnaces, ot' which the following is a specification.

lwiy invention relates to stoves or furnaces iter lnirning` solid fuel or gas, and its object is to combine in one apparatus means for burning either-.solid iuel, such as'eoal, or AFor burning; gas, or 'for burningl both the soli( tuel and the gas at the saine time; and to thereby obtain a inaxiinuni amount of heat troni either or both sources without interiic ence with the combustion oitl either form oif fuel. rinotherobject of iny invention is to provide ineens for conveniently adapting the apparatus especially to burn either form oi? fuel, and to provide ifor an efficient radiation vien. either 'torni et' fuel .is used alone. i ih'lrther object of my viinfention is to pro vide such apparatus t a. n'lininiuin oif first cost and cost or? tallation; and to 1provide ior converting into such apparatus furnaces oi ginallj; designed only tor burning solid fuel.

Lec

invention consists in the combination et parts and in. the details of construction und arrangernent or parte as will hereinafter be more Lully described and claimed.

.. the drzltwings:

Figure 1 is a general perspective View en troni the iront `and illustrating a fur- "e in Vwhich my invention is embodied, et the furnace beingrepresented as 1 away and omitted in order to more readily reveal certain details of my invention; i

Fig. Q is a similar View taken from. the rear;

F 3 is a horizontal cross-section on a )lane correspending= to the line 3-3 ot' Fig. showing the apparatus adjusted tor burning both kinds of fuel; and

Fig. 41 is a partial cross-section similar to 3, but showing the apparatus adjusted for bur solid fuel only.

The furnace which I have chosen for the ini-pose of illustratingthe preferred con- IUrl-fiction and of use of my invention mnnprises the it 1 having the cl y.1n-out und draft opcnl L.' at the front which is closed by a door 3 (Fig. 3); the lire-pot 4' leading;` into a large annular outer flue 13 that passes all around the central' part 9 and has at the bach the outlet tine 14e,y 'which it will be understood leads to the lchimney tor carrying the smoke und other products oi combustion to the outer air. I

rPhe :dre-pot d and deine 4 thus niale up a ksolid-fuel combustion chsinbera and the rrete 5 a nieans therein it'or burningsolid fuel, such coal, coke, Vwood or any other solid 'uel desired to be burned, and to which the parts ina-y be adapted in any 'Well known manner.

The ash-pit 1 is surrounded by a suitable base 15 on which is supported` the easing 16 which3 With the furnace front 17 (Fig. 3,) entirely surrounds the parts just described. The front openings 2, 6 and 9 open through the front 17, and the outlet ilue 1:14 leads out through the rear side of the casing.- The top et the casing is closed except'where the Warm-air pipes 18 (shown in Figs. land. 2' by dotted lines) lead from it in various dii'eotions to distribute the air from the inside of the casing to various parts o'l the housev or other place that is to be heated. The. air

the duct 19 (shown in Figs. 1 and 2 by dotted lines) leading through the casingavall near its bottoni at the rear. All oi these parts just described, beingy old and-Well known, need no r'urther .illustration or description. f

The only ones of the parts ofthe solid fuel furnace just described that require any niodiication at all', are the radiator Sand casing` 16, which modifications are co1nparatively'slight, as will be set iforth hereinafter.

ris will be clearly seen in Fig". 3 and 1, the sides of the casing 16 are spaced some distance outwardly from the outside of the radiator 8 for the free circulation of air' ing ofthe radiator where the Alarge outer annular flue 13 isV spaced away trein the inner part ll or' the radiator. This radiator S is therefore of soinewhat greater diarneter than the deine 5, fire-pot 4; and aslrpitl in this lrind of furnace; and with the spaing of the casing-wall still farther outward, censiderable space is lett all arc-i nd the lower part ot the furnace below the adiator 8 ef;- cept at the 'front where the pa :s 2, 6 and 9 lead iorwa Te roi'n the ash-pit l, dorre 5 and radiator S, respectively, is necessary in order to permit access to the interior ol these parts for reasons well known, and as indicated by the names given to their. in the foregoing description.

In the preferred embodiment 1" iny invention, therefore, l preter to use this kind of furnace construction, because it leaves ainple spaces at the Sider'` and rear ot the solid-fuel-burning part of the 'furnace under the radiator thereof for the installation ot the ineans Ytor burning gas.

Thus,l I provide up ight casings or chambers 20 in these spaces, each of a cross-section tlat is et segmental the rea and extends substantially l from the segmental part toward the and haring' its front side 2l snugly against the inside of the of the wallof the casing' i6 at tha' having' its rear ene spacer-v son laterally7V frein the ront-to-rear l y ..4 and() at lthe fron?, around behind t -e solid `inel-burning part el the rear ends are spaced l to .leave an air passage i fr. .liso these chambers :2O are niade or"- sich width relative to the spa they occupy that the)v leave between the'r inne"` and the inner solirl-iuetbuinirg part oit vfurnaceinner air-spaces 2l, and between ldes of the casing 16, outer air-spaces Also, these chainbers 2G are made et such height ixlatirete these spaces that theyv leave above thein, bi,- tween'lheir tops the betteln or the radiator 8, upper air-spaces ably, these chan i i distance up tiroir tne biV4 air-space 2? is left i Thus, each chamber above, below. inside spaces inclosed bj; the inner and outer spaces con rear through the passage 2 duct 19 through which the c', the casing 1G.

Y Where the front 2l of each chamber vO is against the wall ci. the casing' 16, a suitable opening 28 is provided through the Y casing-wall and the front 2,1'Y nec r the bottoni so that access s had to the lower part elf the chamber ln this lower is a burner 2Q, which, as here shoufn, consists of two tubes 30 branching Jroin a inixer 3l at the front and extending' along substantiallyv parallel -to each othe in contorinity with the curi/'ing` shape ot the chainber cross-section and meeting in a. lll-bend 32 at the rear; each tube having a plurality ot' perlorations o' suitable size and shape and emitting the gas for proper combustion after having; been niiXed with a suitable proportion oi" air at the niixer 3l; the proper proportion and arrangement of these orifices and oi the inixer 3l in themselves being readily deterinined by i skilled in the art. however, it is preierablc i f the orilces 33 the;T 3 1 7 and frein will not thus lessen chamber branching i or not, as i adif'antage because affording a Y y large amount or' i 'f red space arailef rs Jl are supplied n across the nt of the Y base nere shown, ai l o having a, *Je 36 to contre the supply et gas apparent tha other z c openings ,re just inside ann nus receive a plentiful suopli or air through these oeening's 28.

dition to the openings l prefer to sightand auxiliai", air openings short tub-es 37, 38 and 89 that eze intervals approxiniateljyY in radial nu through the outer wall of the t the bottomL and the adjacent 1G. rThus, air may pass uses to the interior ot the bothaniber 20 from the inside oi" but is kept distinct troni the air 25 between the chambers casing` l. Else, theselool; into pe t one t: cha er 2O with the aid lioht A inea-ns inserted co dition the burner et n s or' tl? chaniber i ed converg.

small animals or other objects, each one oi" the pipes 37, 38 and 39 should be provided with a suitable screen 40; which, as here shown, is preferably provided at the outer end oi the tube which opens through the Wall of the casing 16, and is removable troni the tube.

The interior of each chamber :2O above the burner 30 is provided with an ascendingseries of baliles Lil, l2v and i each teiiding across the full width oi thc chamber interior, the first extending entirely to the front 21 but ending short of the rear end of the chamber, leaving an upward passage il; the next batile 42 meeting the rear end 22 but ending` short of the iront end 2l and leaving an upright passage e5; and the next bailie i3 being arranged like the first one all so that there `an upright pas sage i6 at the rear. in each chamber 2O above its uppermost baille at the iront end on the inner side is the outlet opening fi?, and iiues 48 curve inwardly and upwardly and then extend straight upwardly at the respective sides oi the lfuel-intalie 6 of the 'furnace and communicate through openings l?) in the bottom o1"- the large outer annular part 13 of the radiator 8 with the inten r oi? said part at opposite sidesoi the ion waidly extending iiue l2 of this radiator.

llVith this construction and burning` the gras in the loWerinost part oi' the cliainber 207. they products of combustion will pass rearwardly in this lmverinost part, up through the passage #le forwardly and up through the passage reai'wardly.,y and up through the passage i6 and iinally out through the outlet el? and upV through the fine e8 to the radiator 8 Where they must pass aroundthe respective side oi' the large outer annular part 13 to the final outlet or tine le at the rear. Y

lt will thus be seen that when coal or other solid fuel is burned in the iire-pot #i aid is burned in the chambers 2O at `thesaine tiine5 theproducts et combustion iroin both lainds of fuel pass along together around the radiator 8 and out through the iiue ill.

When it is desired to use solid fuel alone without gas. it is desirable to close the conilnnnication between the path oi the products oi" combustion troni the solid Atue and the unheated air spaces in the unused chanibers 30; because the opening` ot tli bottoni oic my tine to the entrance oi" col-d air decreases s eiiiciency. iiccordingly, I provide ineans for temporarily closing' the upper ends of the lines ii8 Where they enter tl e radiator 8. its here slionf'n. this means consists oi a segmental fia-t plate 50 lyingl on the bottoni` ot' the annular part 13 ci? the radiator 8 and fitting 'it .loosely so as to be slidable Vtherearound and having in its middle relatively long and Wide curved slot 50 so proportioned and arranged that when the plate 50 the openuip;9 the inoyenient of the plat' or damper in either direction is prop l the purpose for Wliica the niot'eineir` is eiiccted.
